HULLER AND CLEANER FEEDER FOR COTTON GINS.

Application filed September 1, 1921. Serial No. 497,792.

To @ZZ whom t may concern.'

Be it known that l, CHARLES ROBERT iWOOD, a citizen of the United States, residing at lllemphis, in the State of Tennessee, have invented certain new and useful Improvements in Huller and Cleaner Feeders for Cotton Gins, of which the following is a specication. lThis invention relates to huller and cleaner feeders for cotton gins and it consists in the novel features hereinafter described and claimed.

An object of the invention vis to provide apparatus of the character stated which will effectually and thoroughly clean seed cotton preparatory fory ginnng purposes and with this object in view the huller and cleaner includes a Icasing having a cotton carrying drum 'ournaled therein. A feeding mechanism is mounted up the casing and adapted to introduce the cotton in batches or wads therein and upon the drum. Cotton brushing and hull separating means are located in the casing and adapted to act upon the cotton carried by the drum and doffmg means are provided for removing the cotton from the cotton carrying drum.

A A further object of the invention is `to provide an improved means for feeding the cotton to the' casing and drum whereby the cotton may be introduced into the casing in Vwads or batches and which are subsequently opened up upon the cotton carrying drum preparatory for the action of the hulling, cleaning and separating mechanisms.

In the acco-mpanying drawing Figure 1 is an end view of the huller and feeder. i

Figure 2 is a transverse sectional view of the'same. i VFigure 3 is a side elevation with parts broken away and parts shown in section, the section beingv cut upon the line A-A of Figure 2.

Figure 4r is a detailed fragmentary sec: tional view Vofthe cotton feeding mechanism of the cleaner.

As illustrated in the accompanying draw ing, the cotton huller and cleaner comprises a casing indicated in general as 1. A relatively large drum 2 ris vjournaled for rotation in the casing and is provided upon its periphery with steel pins 39. 'Feed rollers 3 and 4 are journaled in the casing above the drum and are adapted to receive'the cottgn ,between them asrits being lli'ilov A substantially vertically disposed separating board 10 is located in the casing 1 at the side of the drum and spaced therefrom and a screw conveyor 6 is located at the lower edge of the board 10 and between the said board and the side wall of the casing and is adapted to carry off all foreign matter removed from the cotton upon the drum. A relatively small cylindrical doing brush 7 is journaled in the casing at the lower portion of the drum and extends the full v length thereof. The bristles of the brush 7 have Contact with the pins 39 upon the drum as the pins pass by the brush. An inc-lined screen 8 is located below the drum and opposite the brush 7 and spaced therefrom. The screen extends the full length of the drum and brush and a chute or slide board 9 extends from the lower edge of the screen and is inclined under the lower edge of the side wall of the casing 1 as best shown in Figure 2 of the drawing.

A screen panel 12 is mounted upon a hinge 11 and is located over an opening in the side of the casing 1 at a point opposite the upper edge of the separating board l0.

A hopper 13 is mounted upon the top of the casing l and is adapted to receive the seed cotton from an elevator (not shown).

Valve wings 14: and 15 are slidably mounted in the lower portion of the hopper l?, and are carried by arms 1G and 17 respectively. A handle lever 18 is fixed to the arm 1G as shown in Figure l. Inter-meshing gear segments 19 and `20 are carried at the upper ends of the arms 16 and 17 and are pivotcd upon yokes A13 attached to the hopper 13.

Aclutch pinion 21 is slidably niouncfl upon theshaft of the drum 2 and a lever 22 is provided for shifting the clutch pinion 21 in a usual manner. A relatively large gear wheel 23 is journaled at the end of the casing l and the pinion 2l may be moved into and out of mesh withl thesaid gear wheel.

A T-arm 24 is adjustably connected at its lower end with the wheel 23 at a point to one side of the center thereof and the said T-arm is provided at its upper portion with a slot 37 which receives the shaft of the roller 3. A ratchet wheel 27 is mountedup-v on the shaft of the roller 3 and pawls 25 andi26are carried at the ends of the cross head of the T-'arm and engage the ratchet teeth of the wheel 27'. A slotted block 3S is mounted upon the wheel 23 and carries an adjustable wrist pin'28 upon which the lower end of the T-arm 24 is pivoted. A drive pulley 29 is mounted upon the shaft of the drum 2. A pulleyBO is also mounted upon the shaft of' the drum 2. Pulleys 3l and 32 are mounted'upon` the shaft of the cleaning. brushV 5'. A pulley 33 islmo'u'nted upon the shaft of the dofiingbrush 7.' A sprocket wheel 34is mounted upon theV shaft of the drum 2 and a sprocketa 85 is mounted uponv the shaft of the conveyor 6` and are operatively connected by a` sprocket chain in a usual manner and as shown in Figure A spout 36 extends through the end of the casing l and isA located at the end ot thel conveyor 6'. The air and trash space between the separating board 10 andthe side wall ottliecasinglis'l indicated at 44, theV bristles'upon' the brush` '7' are shown at 42 and the' space between the separating` board andthe drum 2f is indicated' at 4l'.

In operation the cotton is fed' into the hopper 13 and upon the-valve wings 14 and l5v and' when readyv to be put through the feeder the valvejwings are moved to the positions as shown in Figure 4 ot'- the drawing, whereby the cottonmay descendand pass between the wings and the feedv rollers 3 and 4. The shafts of the rollers are operatively connected together by gearwheels. By the action of:L the rollers the cotton is forced down' upon the drum'. The operator then usesthe lever 22l and throws the clutch pinionv 21 int'o mesh withv the gear wheel 23 which is rotatedv andthe wrist pin- 28'is carried around the centerl thereof.` This causes the 'F-arm 24 to reciprocate vertically and at' the same time causes the upper portion thereofto oscillate or swing. This movement of the upper part of the T-arm causes the pawls 25 and 26 to engage the teeth of; the' ratchet Wheel alternate-ly and hence intermittent rotary movement is imn parted to the ratchetv wheel and' through the connecting parts to the feed"V rolle-rs 3 4. Thusthe; cotton is drawn or` forced down upon the drum 2 where it is caught by the steel pins 39`and carriedi 1n` underv the wing I4 andV under the feed roller 4, as the drum 2 rotates p ink the directionY as, indicated by the arrow-n Fi ure; 2; l v

The Wings Man *15 upon the feed, roller 4 check the delivery of the cotton to the degree in which the opening between the wings is varied by the manual operation of the wings and loosen the hulls and other foreign matter which may be in the cotton and pass them outwiththe cotton between the wings 14 on the roller 4 on and down through the bristles 40 on the brush 5 which further removes the hulls and other foreign matter from the cotton. The Jforeign matter thus separated from the cotton is thrown of? by centrifugalk force over the top ofthe separating'board 10 into the space 44 and falls down upon the conveyorv Gand is carried off through the spout 3G. The cotton is carried on by the steel pins 39 through the space 41 down to the brush 7 which revolves in the direction indicated by the arrow in Figure 2, and the bristles Ll2 on thei brush 7 remove the cotton from the steel pins 39 and dash it against the wire screenS where any remaining dirt-or trash is knocked out of the cotton and passes through the screen. The cleaned cotton slides down in the chute 9 to the breast o1LA they gin (not shown).

What I claim is l. A cottoncleanercomprisingl a casing, a drum journalled therein for rotation, feed rollers journalled above the drum, means for rotating the feed rollers intermittently and simultaneously, valves movably mounted above the rollers, and' means for manually moving the valves simultaneously to vary and control the size of the delivery opening therebetween. e
